in reply to Display new widgets after MainLoop

(after MainLoop has been called)

Not after the MainLoop. This loop never exits (if you don't destroy the MainWindow, that is).

Instead, you bind events to code (subroutines), which does what you want (e.g. create widgets). Then if a event is triggered, the code bound to this event is executed.

populate a grid managed frame

You just create those widgets as children of the frame:


where $Widget is Button, Frame, Entry, Canvas, ... etc.

[james28909]: another thing i am sick of is hurting others feelings
[1nickt]: james28909 You lost me a bit when you said "show me evolution from intelligence to ignorance". I guess we would have to define the terms, but as I look around at my species and how we are destroying our habitat ...
[james28909]: seems like a person cant even have a belief without hurting someones feelings. i never said my way is the only way. i just said i have pretty good scientific evidence, and then asked for opposing side to present evidence
[james28909]: was downvoted and left without a reply. go figure
[holli]: but then you DO give a fuck
[1nickt]: I don;t think beliefs should be down-voted, just behaviours.
[james28909]: im not quite how to explain it any better nick. you evolved from ignorance to intelligence. not the other way. the universe evolves from gas coulds and debris into planets stars and galaxies ect. it doesnt happen any other way. hence it has ....
[james28909]: some kind of logic behind it
[james28909]: and that is also anothe rpoint i made, i think it has to do with perception of the world around you. most people think of evolution on a human scale. why could life evolve on this planet? because this planet evolved in this solar system. and so on.
[holli]: here's something for you to watch, James. I think you will like it
